Absolutely - this doesn't need to ping anymore and can be implemented as described in the client guide here: http://redis.io/topics/sentinel-clients

"The client should iterate the list of Sentinel addresses. For every address it should try to connect to the Sentinel, using a short timeout. On errors or timeouts the next Sentinel address should be tried.
If all the Sentinel addresses were tried without success, an error should be returned to the client."
